Index of /channels/data/statistics/Re180/balances
The files in this directory (Re180/balances) contain terms in the
balance equation for the reynolds stress and turbulent kinetic energy
extracted from direct numerical simulations of fully developed
turbulent channel flow at Re_tau=180. The simulations are reported in:
- Statistics, Sergio Hoyas and Javier Jimenez, (2008) "Reynolds number
effects on the Reynolds-stress budgets in turbulent
channels", Phys. Fluids, Vol. 20, 101511.
- Data, J. C. del \'Alamo and J. Jim\'enez (2003) "Spectra of the
very large anisotropic scales in turbulent channels", Phys.
Fluids Vol. 15 No. 6, pp L41-L44.

This directory contains 5 files named Re180.bal.<extension>, where
the extension indicates the contents of the file. The extensions are
kbal -- balance of the turbulent kinetic energy
uubal -- balance of the streamwise velocity variance
vvbal -- balance of the wall-normal velocity variance
wwbal -- balance of the spanwise velocity variance
uvbal -- balance of the Reynolds shear stress
There also are 5 files named Re180.std.<extension> containing the
standard deviation of the balances.
Note that some of the quantities reported in these files should be
zero by statistical symmetries.
Please report any problems with the data to S. Hoyas
